Java中LIST轉換爲數組，數組轉換爲LIST實現

一種很精簡的方法，實用簡單

 package xiaoming.com; 
import java.util.*;
public class Ugly{

	public static void main(String ap[]){
		String[] a2 = new String[] { "srt1", "srt2", "srt3", "srt4" };
		List list=Arrays.asList(a2);
		System.out.println(list);
		String []a3=(String[])list.toArray(new String[list.size()]);
		System.out.println(a3[0]);
	}
	
}

還有很廣泛的方法實現 代碼以下

package xiaoming.com;

import java.util.*;
public class Ugly{

	public static void main(String ap[]){
		String[] a2 = new String[] { "srt1", "srt2", "srt3", "srt4" };
		List list=new ArrayList();
		for(int i=0;i<a2.length;i++){
			list.add(a2[i]);
		}
		String a3[]=new String[list.size()];
		for(int i=0;i<list.size();i++){
			a3[i]=(String)list.get(i);		
		}
	}
	
}
